Embodiment 1

[0019] Such as figure 1 As shown, a light intensity detection device for agricultural big data includes a daylighting box 1 and a light intensity detector 2, the top surface of the daylighting box 1 is a transparent glass plate, and a horizontally arranged transparent box 3 is installed in the daylighting box 1, transparent The box body 3 is filled with mixed gas of nitrogen dioxide and dinitrogen tetroxide, the mixed gas is an equilibrium mixture, and the equilibrium moves with the change of temperature, and the reaction equation is N 2 o 4 ==2NO 2 (reversible), the side wall of the transparent box body 3 is communicated with an air bag through an air guide tube, and when the mixed gas of nitrogen dioxide and dinitrogen tetroxide is heated and expanded, part of the mixed gas enters the air bag under the action of air pressure to play a buffering role and avoid The air pressure in the transparent box 3 is too large, the bottom of the transparent box 3 is equipped with a phot...

Embodiment 2

[0026] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that: a cavity 14 is provided in the mounting seat 11, and a plurality of exhaust pipes 15 are fixedly connected to the side wall of the mounting seat 11, and the plurality of exhaust pipes 15 are in the form of The annular arrays are arranged and communicated with the cavity 14 , and the included angle between the exhaust pipe 15 and the tangential direction of the mounting seat 11 is 60°.

[0027] In this embodiment, during the downward movement of the permanent magnet ring 8, part of the gas in the adjustment cylinder 5 is discharged from the exhaust pipe 15, and the gas generates a reverse thrust on the exhaust pipe 15, because the exhaust pipe 15 and the mounting seat 11 The included angle in the tangential direction is 60°, the thrust acts on the mounting base 11, and a torsional component force is generated to it, then the mounting base 11 drives the light intensity detector 2 ...

Abstract

The invention belongs to the technical field of agricultural big data, in particular to an illumination intensity detection device for agricultural big data. The device comprises a lighting box and alight intensity detector. The top surface of the lighting box is a transparent glass plate; a transparent box body which is horizontally arranged is mounted in the lighting box; the transparent box body is filled with mixed gas of nitrogen dioxide and nitrogen tetroxide; a photovoltaic panel is mounted at the bottom of the transparent box body; an adjusting cylinder which is vertically arranged ismounted on the side wall of the lighting box; an electromagnet is installed at the bottom of the adjusting cylinder, an induction coil is wound around the electromagnet and electrically connected with the photovoltaic panel, a permanent magnet ring is slidably connected to the inner side wall of the adjusting cylinder, and the upper end of the permanent magnet ring is fixedly connected with the inner top face of the adjusting cylinder through a reset spring. The device can detect the illumination intensity at different heights, facilitates the scientific regulation and control of the plantingdensity and interval of two types of crops, can achieve the automatic dust removal, and avoids the measurement result error caused by the shielding of dust.

Description

technical field [0001] The invention belongs to the technical field of agricultural big data, and in particular relates to a light intensity detection device for agricultural big data. Background technique [0002] With the practice and expansion of the concept of agricultural big data, the information flow within agriculture has been effectively extended and deepened. In the process of agricultural big data, the detection of natural environments such as light intensity, soil, atmosphere, and water quality, and the collection of relevant information and processing are particularly important. [0003] In the process of crop planting, interplanting (interplanting) is often used to plant two different crops together to improve economic benefits. Most of the heights of the stems and leaves of the two crops are different, and the taller crops have a higher demand for light. Large and short crops have a small demand for light, while most of the traditional light detection devices...
